BOX.

Application led April 13, 1922. Serial No. 552,342.

This invention relatesto improvements in boxes made of fibre or paperboard or the like and consists of the matters hereinafter described andmore particularly pointed out in the appended claim.

The object of the invention'is to provide a collapsible fibre or paperboard box capable A of top loading which may be, manufactured at aminimum cost of labor and material and which has a top closure that maybe nailed shut, so that it can be easily opened by the use of thefamiliar nail puller, when the contents of the box are to be inspected,and again nailed in closed position.

The advantages of the invention will appear as I proceed with myspecification.

In the drawings: Figure 1 is a perspective view of the improved ,box;Figure 2 Vis a partial top plan view of the box with the top closuresturned back 1n open position;

Figure 3 is a transverse, vertical cross section of the box in a planeindicated by the line 3 3 of Fig. 1;

Figure 4 is a longitudinal, vertical section of the box in a planeindicated by the line 4-4 of Fig. 1;

Figure 5 is a plan view of the blank to form the box;

Figure 6 is a perspective View of a wood bar included in the boxstructure;

Figure 7 is a partial perspective view of a corner of the box.

Referring now to that embodiment of the invention illustrated in theaccompanying drawings 10 indicates the body of the box, which, as shown,is somewhat elongated and is wider than it is deep, although theseproportions may be varied to meet the requirements of the box. 11, 11indicate the sides of the box; 12 the bottom of the box; 13, 13 the endsof the box; and 14 indicates the top closure, which in this caseconsists of two flaps 14a, 14, each somewhat wider than one-half thewidth of the box, so that they overlap, when in closed relation, asclearly appears in'Figures 1 and 3.

The box in its preferred form is made from a single blank of paper (seeFig. 5) which is cut and creased to fold into box form. The main lengthof the blank is creased along transverse parallel lines 15 to providethe bottom 12, the sides 11, 11

and the two cover iiaps 1 4, 14a,-all of which are laid out side by sidein proper order, with their lengths extending transversely of the blankand with the flaps 14, 14L1 at the ends of the blank. 16, 16 indicateparallel, spaced, crease lines, extending lengthwise of the blank anddefining the ends of the sides 11, 11 and ofthe bottom 12. The flaps 14,142t extend at their ends 14, 14b somewhat beyond the longitudinalcrease lines 16, 16, which terminate at the transverse crease lines 15,15 upon which the fiaps14, 14a are designed to fold. The blank haslateral extensions intermediate the flaps 14a, which yextensions are cutto define end flap extensions 11a, 11a on each of the box side-forming`parts 11, 11 of the blank and end flap extensions 12a, 12El on the box'bottom-forming part 12 of the blank. When the blank is folded into boxform, said flap extensions provide the ends of the box,- the flapextensions 12a being each of the width and depth of the box andthe flapextensions 11a being of the depth of the box along the crease lines 16,but having a length at right angles to said crease lines somewhatgreater than the width of the box so that they will overlap, whenfolded, one upon the other, as appears in Fig. 3.'

The box is s et up by folding the blank to bring the sides 11, 11 into aposition vat right angles to the bottom 12, whereupon the side end flaps11, 11a are folded one upon the other and the bottom end flap 12a isfolded up outside the said side end flaps. The several flaps named aresecured in this yposition-in which they form the end walls of theboxe-by transverse pairs of wood cleats 17, 17 Thesaid wood cleats areof a length substantially` equal to the width of the box and arepreferably wider or" deeper than they are thick. Each pair of woodcleats is attached, -by stapling Oor otherwise, to the several end flapextensions, forming the end of the box, with said end flaps embracedbetween them and with the Ctop edges of the cleats, providing a topsurface against which the top Haps 14, 14a may be closed, as shown4 iapsis manifest,said end extensions overl lying and closing upon the outsideend cleats 17, as is shown in Fig. 7.

After the box is' loaded throughits open top, the top closure iaps 14aare folded down, one overlapping the other, upon the top edges of theends of the box comprising the wood cleats 17, 17 andend flap extensionsof the sides and bottom-respectively, 11a, 11 and la-embraced betweenthem. Said tov closure flaps are then nailed at their en s to the endsof the box thus comprised,-the nails readily taking into the compositenailing edges of the box,-pref erably through the fibre or paper boardsheets between the wood cleats.

The wood cleats provide the required resistance to the hammer shocks dueto nailing the top closures in'place and in addition, reinforce the boxagainst stacking and loading strains. With the fibre or paper end partsembraced between them, said wood cleats furnish composite nailing seatsfor the top closures, since the nails, while intended to be driven intothe fibre, will manifestly take as well into the wood or more usuallyinto the Wood on one side and into the fibre on the other.

The novel box is of particular advantage for use in shipping lightvegetables, such as head lettuce, cabbage and the like, all of whichrequire inspection and the necessary oppning of the box in transit.

The oxes are shipped flat to the packers or users, as in the case ofother collapsible boxes, the wood cleats either being sent with thefibre or paper blanks or being supplied 'by the the users, as may be.commercially convenient.

lVhile in dcscribin my invention I have referred to several etails ofconstruction and arrangement of parts, it is to be understood that theinvention is not thereby limited except as may be pointed out in theappended claim.

I claimas my invention A box made of a single blank of fibre or paperboard, the blank being cut and creased to provide a bottom wall, twoside walls and two top closure flaps adapted to overlap along a medianline of the box, the bottom wall having end extensions to provide endsof the full depth and width of the box, and the side walls having endextensions which are folded against the end walls to substantially coversaid end walls, and wood cleats, a pair foneach end of the box,embracing the extensions forming the end of the box between them andbeing'stapled thereto, said' wood cleats extending the full width of thebox and the top closure flaps of the box being folded down upon saidwood cleats and nailed to the composite seats thus pro' vided.

In testimony that I claim the foregoing as my invention, I aiix mysignature this 6th day of April, A. D. 1922.
